e new FARM GATE.

Application filed November 11, 1920.

e 'fito/1L 'it 'may' conce/m it known that l, @rims NinLsnN, a citi i" tlc United States. and -resident ol' T) X uthven. in the county ot' Palo Alto and bat-ate ot iowa, have invented a certain new and useful Farm Gate, o. which the following is a specitil ition.

The object o'j my invention is to provide :1 gate ot simple.y durable and inexpensive ronf-xtruction. ot the class in which the gate may bc opened or closed by an operator in a vehicle or on toot. when approaching or leaving; the gate by simply pulling upon the roue.

V L; specifically it is my object to provide ot this class in which one end ot' the ttor movement` gate proper is o its other eues upwardly and e entire gate longittuilinally.y 'ng a gate which is firmly in" ui l I' n v v and securely si'ipported either when it is in its open or in its closed position. or when being moved.

turther objectis to provide an ininroved automatic latch device for the gate to co-act with a gross-piece ot the gate that it is supported on guide wires. which latch device serves to aid in holding the gate i'irmlv in position when closed and which is automatically released upon the initial movement ot the gate controlling rope.

My in cation consists in the construction, arrangement and combination ot the various parti* ot the gate, whereby the objects Contemp ated are attained as hereinafter more itully set forth, pointed out in my claims and illustrated in the accompanying d'faivi in which;

Figure 1 shows a side elevation oit a gate einbodying my invention. ,in this iignre, the gate is shown in its closed position by solidV lines, in partially open position by dotted lines7 in a completely open position bv dotted lines.

i Figure 2 is a persl'iective view ot the gate in a closed position and Figure 3A shows an enlarged detail perective view illust-ratingthe parts ot the 5c latch device.

Referring to the accompanying' drawings, l have used the reference numeral. to indicate generally the main supporting frame of the gate operating device. This is prefer` ably made di pipe and comprises two uprights with their lower ends rmly placed Speciicaten e1 .Letters Patent Patented [ru-gri, 8, tf

in the ground and a connecting cross-piece at their upper ends. Pivotally connected with the lower ends of the nprights 10 is lever 11 capable ot swinging back and 'forth between the uprights 10. The gate proper, which may be ot any ordinary construction is indicated by the numeral 12 and is pivotally connected with the upper end ot the lever 11. Ait one end ot the gate 12 is a combined gate guide and latch device consisting ot a cross-piece 13 rigidly secured to the gate 12 and provided at its ends with openings to receive guide wires, as hereinafter described.

At the outer end of the gate I have provided a station-ary post 1d, for the purpose only ot preventing lateral. movement of the outer end ot the gate. For this purpose l preferably form this post of pipe and double it at its upper portion and its sides are spaced apart tar enough to receive the end ot the gate between them.

Fixed to the lower end portion of the uprights 10 and extending horizontally in a direction away trom the gate opening are the guide wires 15, which pass through the openings in the combined guide and latch device 13, the outer end of the guide wires 15 being supported in the post 16.

Pivoted to one of the uprights 10 is a latch member 17, having a curved portion, a shoulder 19 and also provided with a curved slot 20, Slidingly mounted in the curved slot is a pin 21, attached to a slide bar 22, mounted on the adjacent upright 10.

Mounted upon the portion of each upright 1G is an adjustable bracket, to which is pivoted an arm 23, which arm extends outwardly and upwardly7 away from the gate. Connected with the central portion of the arm 23 is a rope 24, passed over a pulley 25, on the upright 10 and extended downward and attached to the lever 11. Slidingly mounted in the outer arm 23 is a rope 26, its movement in the arm 23 being limited by the stops 27 on the rope. rlfhe outer end of the rope is lett hanging downward from the arm 23 to be grasped by the operator. These ropes 26, are connected to the side bar 22.

In practical use and assuming that the gate proper is in its closed position it is obvious that it will be firmly held in said position because the cross-piece 13 rests against one side of the Jframe 10. The outer end of the gate has its lateral movement pre-A und vented by the post 1d and the other end of the gate is held against movement by the latch 17 engaging the member 13, thus supporting the gate against movement in any direction and its accidental displacement. The operator in a vehicle approaching the gate may conveniently grasp and pull the rope 26. rlhe iii-st result of such movement is to litt the slide bar 22 and the latch device 1T, then the next result is to lower the arm Q53 and thus pull upon the rope 24;. This oscillates the lever 11 and raises the outer end ofA the gate. rthe other end o1"- the gate is guided to slide upon the guide wires 15 and a'tter the gate has passed to the position shownv by dotted lines at the central portion of Figure 1, it will continue to move by gravity to its wide open position. attention is called tothe fact that throughout the entire movement of the gate and when in its open position it will be guided and supported by the cross-piece 13 and the guise wires 15 against lateral or twisting strains, thus relieving all twisting strains from the point et connection between the lever 11 and the gate. Further more, when the gate is in its closed position it is iirmly and viinrnovably `held against any strains to which it might be subjected. lts outer end cannot be elevated on-aecount oit the latch device.

It cannot move laterally on account oit the post 1st. However, when the latch is released, the outer end of the gate swings upward, thus permitting it to clear itself from snow or .any other obstruction on the roadway. By providing an adjustable bracket and supporting the arms 23, the said arms may be extended to any angle or into any position most readily accessible to the oper ator. After the gate is opened, thesearins 23, may readily and easily be swung up out et the way ot' a large or high load on a vehicle passing through the gate way. Then the gate swings to a closed position the cross-piece 13 strikes the curved edge 18 of the latch so that the free end et the latch is elevated to permit the cross-piece 13 to pass baelr oit the shoulder 19.

l claim as my invention 1. rl`he combination with a gate, ot an upright trame, a lever pivoted to the lower portion et the upright traine and also pivoted to the upper central portion of the gate, means for swinging the lever to move the gate longitiulinally, a cross piece lined to one end ot the gate and having two openings therein, two wires tired to the upright extended through said openings in substantially horizontal positions, supporting posts for the outer ends et said wires, said. wires being extended in, horizontal positions pai allel with the opposite sides oithe gate whereby when the said lever is moved one end oit the gate will be tilted upwardly and the other end will be guided in substantially a horizontal position during its longitudinal movement.

2. The combination with a gate, ot an upright it 1amc, a cross-piece fixed to one end or the gate, guide wires parallel with the gate and extended through said cross-piece, a latch device supporte-d on said upright traine and designed to cofoperate with said ciosspiece, a post at the outer end o'll the gate designed to engage its sides to thereby prevent lateral swinging movement., two ad ustabie brackets on the upright traine, and `arm pivoled. to each, a rope iixed to each arm, a pulley on the upright traine for each rope, a lever 'l'ulcrumed at its lower end to tbc upright iframe and having the said ropes f attached to it, a latch rope for each arm having a limited sliding movement relative thereto and connected to said latch device, substantially as and ttor the purpose stated.
